lookup filter formula not displaying the correct contact

Hi there,

I trying to write a formula in a lookup filter so that when a user enters a contact’s name, it will only display contacts that are associated with the same parent account. The lookup filter is in a Flow.

Here’s is the formula:

Id Not In ({!PreviousStudentIds}) AND IsPersonAccount = TRUE AND NU__IsMemberFlag__c = false AND NU__PrimaryAffiliation__c = '{!TroupAffiliationId}'

We use Person Accounts data model and a custom object called Affiliation. The Accounts objects has a self-lookup relationship.

User-added image
The Affiliation object has a lookup (NU_ParentAccount__c) to the Account.

User-added imageTroupAffiliationId is a variable in the Flow that stores the parent account.
User-added image
The filter formula is still displaying contacts that are NOT associated with the same parent account.

Any suggestion as to how to fix the formula?
